Absolutely there is reason to believe that. A lot can happen in two days: bug fixes, getting the last interview in, getting a sign off because a manager was on vacation before something was approved, giving a speaker who has a sore throat/weak voice some time to recover and/or find a replacement, or for that matter just trying to get an update out while dealing with a server issue. I feel the real key here is to remember how suddenly this announcement changed via tweet yesterday. This wasn't an early delay like we had for SL launch, this was the day before. If it were for something like a 9.2.5 announcement, we would have had a bit more notice as that isn't a last minute thing.
